The answer is B. Draw conclusions
Well if you do 4.75 ft times 42, you get 199.5ft. Then subtract 199.5 ft from 240ft and you end up with 40.5 left over. Yes, this is reasonable.
Answer: b
Step-by-step explanation:
Sin = opposite/hypotenuse
Cos = adjacent/hypotenuse
Sin A = BC/AB
Cos B = BC/AB
Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
Z = (score - mean)/sd
-1.75 = (x - 38)/4
Multiply both sides by 4:
-7 = x -38
Add 38 to both sides:
x = 31
